LUXY is a type of Video file format with the extension LUXY. A LUXY video file is a digital multimedia container format file type that Uses improved recording methods to optimize storage. It is commonly used to store video and audio using its own matrix encoding method, sometimes accepting duplicate codes to minimize capacity without needing to compress the file. Unlike most modern container formats like MP4, AVI, MOV,... It does not allow streaming over the Internet. The only filename extension for LUXY files as defined by the specification is .luxy.

History

edit

First published in 2011, although there are advantages in terms of storage, however, due to many limitations of not being able to play videos cross-platform and on the internet. In addition, it uses it's own set of codecs and a "write less, read more" writing rule that makes the players waste a lot of effort due to having to run complex algorithms and handle duplicate codes to play. In addition, the ability to convert formats is also very limited. Therefore this file type is not commonly used.[1][2]

Though digital online services that operate on computers have become popular since around 2010, these systems typically remain open, providing the developer with tools to take advantage of cross-platform play. The Steamworks API offered to developers through the service enables cross-platform play to be used on these different operating systems while taking advantage of the friends, communication, and matchmaking features offered by Steam.[3]

Up to date, no other versions have been published other than the LUXY-2011 version.(According to statistics until 2019).[2]

Usage status and popularity

edit

This file format is almost absent on social networking platforms and public players.[1] [2]Most people only use it for long-term video storage purposes in conditions of limited storage devices. LUXY file format only stores very limited encoded information about pixels and even accepts duplicate Bytes for many predefined results and has it's own algorithm to select the correct result. Additionally, when identifying Bytes that are nearly similar to Bytes in the library, the writer will only note the change without writing the Byte. In the original OS/2 DIB, the only four legal values of color depth were 1, 4, 8, and 24 bits per pixel (bpp)[4]. Contemporary DIB Headers allow pixel formats with 1, 2, 4, 8, 16, 24 and 32 bits per pixel (bpp).[5] GDI+ also permits 64 bits per pixel.[6]

Playing videos in this format is also laborious, so most players do not support it. The official software dedicated to playing this format is Luxy Viplay.
